SOFA-BED.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed July 30, 1906. Serial No. 328,413.

To all whmn it may concern:

Be it known that I, RUDOLPH DEIMEL, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds, of which the following is a specification.

The main objects of this invention are to provide an improved, strong, simple, and effective form of locking-hinge for sofabeds to provide an improved connection between the base and the carriage which supports the seat and back, and also to provide an improved structure of back, seat, and base, whereby the carriage is located mainly within the back and seat, so as to permit the space in the base to be utilized for storage of bedclothing without interfering with the operation of the carriage.

These objects are accomplished by the structure shown in the accompanying drawings, in which Figure 1 is a transverse vertical section of a sofa-bed constructed according to this invention and showing the back and seat in their normal positions when used as a sofa or davenport. Fig. 2 shows in vertical section the back and seat in the position which they assume when the same have been pulled to the front of the base on their carriage and tilted so as to bring the back to the horizontal position, the seat being elevated to the position in which the same is locked by the hinge just previous to being disengaged and lowered to form a bed. Fig. 3 shows an end view of Fig. 2, partly broken away. Fig. 4 shows both back and seat in the horizontal position for forming a bed. Fig. 5 is a top plan of Fig. 4, partly broken away.

The back 1 and seat 3 of the sofa or davenport serve as a pair of bed-sections. The back 1 is pivotally secured at 2 to the seat 3 and also to the upright member4 of the carriage. The hinge forming the pivotal connection between said parts at each end is formed of the pivotally-connected wings 5, 6, and 7. The seat 3 has secured to its side a hinged plate or locking member 8, the same being pivoted at 9 to the plate 10, which is rigidly secured to the seat 3. The back 1 has a spring 11 secured at the inside of each of its side walls. Said spring is secured at its rear end to a block 12, which holds its .rear end inwardly from the side wall of the member 1 and causes said spring to roject toward the line of said wall at an ang e, as shown in Fig.

down to the horizontal position.

5. The forward end of the spring 11 bears against the hinged plate 8, when the parts are in the position shown in Fig. 2, and thus holds said hinged plate in a suitable position to bear against the end 13 of the member 1, which serves as a stop to hold the parts in the angular position shown in Fig. 2. A guide14 is also secured to the inside of each side wall of the back 1. When the seat is tilted to the left of the position shown in Fig. 2, so as to release the plate 8 from the spring 11, said plate will hang in a substantially vertical position out of alinement with the stop 13. WVhen said seat 3 is now turned down to the position shown in Fig. 1, the plate 8 will pass between the spring 11 and the guide 14. Said guide is placed at an angle to the spring 11, as shown in Fig. 5, and serves to move the plate toward the wall of the back 1, so that when the seat 3 is again raised to the position shown in Fig. 2 the plate 8 will pass down between the spring 11 and the side wall of the back 1.

The back 1 and seat 3 are both movable from the back to the front of the base 15 on the carriage 16. Said carriage travels on the base on rollers 17. At each side of the carriage is a projecting rib 18, which runs in a grooved track 19 and serves to prevent the carriage from being jolted or tilted out'of its proper position on the base. The base is made hollow in the form of a 'boX suitable for storage of bedclothing.

The back 1 and seat 3 are recessed to receive the carriage, so that the latter does not occupy unnecessary spacein the base. The seat 3 is provided at each end with a pivoted prop 20 for supporting said seat, as shown in Fig. 4.- The spring-pressed pin 21 serves for holding the prop 20 up within the seat when the parts are in the positions shown in Figs. 1, 2, and 3. The arms or side pieces 22 are secured to the sides of the base 15 and serve as arms of a davenport. The tracks 19 are rigidly secured to the inside of these arms.

The operation of the device is as follows: IVhen the parts are in the position shown in Fig. 1, the device forms a sofa or davenport. In order to extend the parts to form a bed, the seat 3 is raised slightly at the forward end and pulled to the right of Fig. 1 until the carriage 16 is at the front of the base 15 or at the right of the drawing, as shown in Fig. 2. The seat 3 will now be tilted upwardly, and this at the same time will tilt the back 1 The seat is prevented from falling to the horizontal position through the plate 8, which bears against the end or stop 13 of the back 1. In order to release the plate 8 from said stop, the

seat 3 is now tilted toward the left of Fig. 2,

moved by means of the guide 1 1 to a suitable position for being again engaged by the spring 11 will again be thrown into contact with the stop 13. By tilting the seat 3 to the right of Fig. 2 the back 1 will be raised and the parts may be moved along the base on the carriage to return the same to the posi tion shown in Fig. 1'.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a pair of bed-sections, pivoted together, one of said sections having a stop, and the other having a hinged member adapted to have contact with said stop so as to lock said sections in a certain relative position, means for urging said member into contact with the stop, said member being arranged to swing free from said stop when not engaged by said means, and a guide for causing the engagement of said member by said means through the relative movement of said sections.

2. The combination of a pair of bed-sections, pivoted together, one of said sections having a stop, and the other having a hinged member adapted to have contact with said stop so as to lock said sections in a certain relative position, a spring for urging said member into contact with the stop, said member being arranged to swing free from said'stop' when not engaged by said spring,

, and a guide for causing the engagement of said member by said spring through the relative movement of said. sections.

A 3. The combination of a pair of bed-sections, pivoted together, one of said sections having a stop, and the other having a hinged member adapted to have contact with said stop so as to lock said sections in a certain relative position, means for urging said member into contact with the stop, said member being adapted, through gravity to hang free from said stop when not engaged by said means, and a guide for causing the engagement of said member by said means through the relative movement of said sections.

1. The combination of a pair of bed-sections pivoted together at their ends, one of said sections having a member hinged therei I to, out of alinement with the other section and adapted to swing into contact with its end, means for urging said member into contact with said end, said member being arranged to pass said end when not engaged by said means, and a guide for causing the engagement of said member by said means through the relative movement of said sections.
